Legacy: JBoss probes and sensors

Discovery identifies a Linux JBoss application server using probes and sensors.

Linux

This process describes the use of probes, which are active on your instance if you upgrade. For new instances, Discovery uses the JBoss pattern.

  1. The UNIX - Active Processes probe detects a running process that matches an org.jboss.main entry point parameter.
  2. If there is a match, a record is created in the JBoss Application Server [cmdb_ci_app_server_jboss] table. The following probes are also triggered:
    • JBoss - Find web.xml list: The sensor of this probe populates information in the Web Application [cmdb_ci_web_application] table if applicable.
    • JBoss - Get jboss-service.xml: The sensor of this probe populates information in the Web Service [cmdb_ci_web_service] table.
  3. The JBoss - Find web.xml list probe searches for the web.xml files of JBoss application server. The probe uses the classpath parameter in the running process, and then searches in the related server\default\deploy directory for the JBoss installation.
  4. If associated web applications reside in the server\default\deploy directory, the JBoss - Get web.xml probe triggers for each application. This probe reads the web.xml file for each web application and the sensor populates additional information to the Web Service [cmdb_ci_web_service] table.
  5. The Boss - Get jboss-service.xml probe uses the classpath parameter in the running process to search for the jboss-service.xml file in the related server\default\conf\ directory for the JBoss installation.
  6. If the probe successfully finds the jboss-service.xml file in the server\default\conf\ directory, the sensor reads the contents of the XML file. It then creates additional records in the Web Service [cmdb_ci_web_service] table as necessary.
